Under the rapid development of China's urban and aging increasingly serious situation, it increases the demand for urban parks, which also park construction and development put forward higher requirements. Now, some park landscape construction appears "not in use" or "not use" embarrassing situation, which is the lack of understanding of user preferences are not unrelated. From the perspective of visual preference starting to learn how different people use different preference of the park, according to the needs to build or transform the landscape, the goal of this paper is to study.This article will be evaluated by quantitative methods, in accordance with the theory of landscape visual preferences, by reading literature and interrogation experts to find and identify indicators of landscape visual preference evaluation. In determining indicators of landscape visual preference evaluation system, the use of certain methods of collecting and processing relevant data, to determine the index weights. The constructed landscape visual preferences for the system to evaluate the actual object, and the results were analyzed, and improve the program. Comments and conclusions about Huanhuaxi landscape visual preferences are as follows:(1) Construction of landscape visual preferences evaluation system. Because prior research in the visual landscape preferences are qualitative evaluation, because they have no quantitative evaluation, visual evaluation methods herein for reference and landscape aesthetics evaluation and build evaluation system of landscape visual preferences, were established 25 index layer, and through proven its usefulness.(2) AHP method and the SD method of landscape evaluation consistent visual preference.

Evaluations from people in different gender, age, landscape knowledge, frequency and areas tend to be the same. AHP method involving the specific targets, on a more detailed analysis and clear; SD method can only be down to whether the level is somewhere in the landscape preferences, be combined with a comprehensive analysis of other factors, compared with AHP method, not enough clarity at a glance.(3) Visual preferences of three major scenic in Huanhuaxi park are better, but differences. Egret Island area varied topography, abundant landscape modeling and landscape visual preferences strongest degree. Wanshu mountain area vegetation is rich, but the tree-lined trail scale and proportion of poor degree of harmony, a good degree of visual landscape preferences. Changlang Lake area is flat, single landscape modeling, therefore weaker degree of visual landscape preferences.(4) Huanhuaxi park has its advantages in terms of landscape visual preferences,but is also inadequate. Advantages are:the degree of pleasant atmosphere, echoing the overall image of the city situation, orderly and smooth roads and the like; there is inadequate: craftsmanship standards, visual impact and the like.
